处理单名多值表单的详解
就使用一个简单的可多选的select：
<?php
echo<<<EOT
<form action="" method=get>
<select name="listVar[]" multiple="multiple" size=3>
<option>first</option>
<option>second</option>
<option>three</option>
<option>four</option>
<option>five</option>
</select>
<input type=submit value=提交 name=submit>
</form>
EOT;
/*输出GET到的值（数组）*/
if (isset ($_GET["submit"])) {
foreach($_GET["listVar"] as $value){
echo $value."<br>";
}
}
?>
复制代码 代码如下:
<?php
echo<<<EOT
<form action="" method=get>
<select name="listVar[]" multiple="multiple" size=3>
<option>first</option>
<option>second</option>
<option>three</option>
<option>four</option>
<option>five</option>
</select>
<input type=submit value=提交 name=submit>
</form>
EOT;
/*输出GET到的值（数组）*/
if (isset ($_GET["submit"])) {
foreach($_GET["listVar"] as $value){
echo $value."<br>";
}
}
?>
